I ordered 6 pcs. of which only 2 worked out of the box. Four had components either dropped off the board already at arrival or during handling and assembly. I managed to solder them back on the board and three where back in business, however the last has a "heavy load ~25 ohm" at the output of the MAX8903A LiPO so no luck here. I can't find the short so probably a defective component or some short underneath a component - given up. I think the product and function is great, but soldering quality is terrible. I adjusted the max charging current Ichg as well as the Iin according to the datasheet of the MAX8903A, since the resistor value calculations wasn't in the product documentation.
